The #2 was McCloud's first real experiment with trying to find a locomotive big enough to move heavy lumber trains up the steep grades while yet being nimble enough to negotiate the many curves and lightly built track. The #2 marked a technological inovation of sorts, and as such it got a substantial amount of period press. Unfortunately it suffered from numerous mechanical problems and spent more time either waiting for replacement parts to arrive from the east or getting repaired in Southern Pacific's shops in Dunsmuir than it did in service. Even when operable the machine failed to live up to expectations; for example, the railroad complained in one letter to Stearns that the #2 would only haul six cars of green lumber up the grade west of McCloud when they thought it should haul more. The problems caused the railroad to rid itself of the locomotive by early 1900.

A drawing of the #2 that appeared in an article about the machine in a 1900 edition of Engineering News. The inclined cylinders drove the drive shaft that ran the length of the locomotive, which in turned powered one of the axles in each truck. The side rods transferred the power to the other axle.
